1.	The opening near the bottom of the vessel shown in the figure has an area `A`. A disc is held against the opening keep the liquid from running out. Let `F_(1)` be the net forces on the disc applied by liquid and air in this case. Now the disc is moved away from the opening a short distance. The liquid comes out and strikes the disc in elastically. Let `F_(2)` be the force exerted by the liquid in this condition. The `F_(1)//F_(2)` is
Answer» Correct Answer - 2 `F_(1)=DeltaP(A)=rhoghA` `F_(2)=rhoAV^(2)=rhoA(2gh),(F_(2))/(F_(1))=2`
